It's Total Defence Day on 15/2/06, we had our mock chemical attack exercise.
Here are the photographs taken on that day.

We had to cover the windows with plastic sheets. Check out my macho boys at work.






Here are the girls at work.
They sealed the doors with masking tape.



Of course, in a real emergency, we are expected to stay here for hours, thus we also needed to construct a toilet.



Let's take a peek inside the toilet. Mark gamely posed in the toilet for me.


Well, after this exercise, I concluded that I cannot rely on my macho boys on sealing the windows as they had artistically created tiny holes in the plastic sheets. As for the toilet, before you use it, make sure you've trained your calves muscles.
